To ail whom it may concern.'

Be it known that I, OswiALD SCHLAUPITZ, a Citizen of the United States,anda resident of Vthe city ot Canton,fcounty O15-Stark, and State ofOhio', Vhave invented a certain new and useful Improvement vin GaugingMachines, of which the following is a specification.

My invention 'relates to gai'iging machines andhas for its principalobject a machine' 1n rwhich a roller for roller bearings andthe like can`be lgau'ged at one setting for size, 'taper and circularity Theinvention oonmachine with spaced gauging means, said means havingmembers contacting with a `roller `at spaced points on the bearingsurface thereof, whereby thesiz'e or the roller is'gauged, the taperthereof is" indicated by the relative positions-ot the -po'inters'of thetwo gauging means, andthe roller is shown to be round or Out-o-rounddepending upon whether the pointers are stationary as the roller isrotated under the fcoritact -membersor whetherv they pointers niove. Theinvention further consists inthegaugingmachine andin the partsand-combinations of parts hereinafter described and claimed.

In the drawings which form partfot this lspecifica'tion and whereinvlike reference "characters indicate like parts wherever they l y i Fig.1 is a side elevation of a gauging machine embodying my invention;

vFig. 7 is ay sectional view on the line 7;'-7 otFig. 1 and Fig. 8 is adetail sectional View' taken at right anglestosection 5155.

A housingfl is mounted on a sui'table'base 2. Projecting' from the lowerfront of the housingrare spaced ring-shaped lugsthat `are inclined fromthe vertical. Slidably mounted in alining hole-s in said lugs is a hnewrou 4 to' whehvis'seeured a longitu# dinally extending key 5 that fitsin a keyvway 6 in the lower lug. The middle portion 7 of said Vhollow.rod is threaded and a threaded nut 8 ismou'nted thereon between vmeansof pins v12 fitting in holes in the seat and rod and is held on the rodby means of a threaded bolt 13, awasher 14 that closes the lower end ofthe hollow rod and a nut 15 that'bears against said washer. Fitting ina' suitable recess in the lower lug 3 is a spring 16 that bears againstthe washer 14, such spring serving to take uplany looseness between thehollow rod and its adjusting nut 8.

The block y10 isheldin position on the seat 9 by suitable screws 17. Theblock 10 lnay be removed from the seaty and replaced with' la differentblock, and thus the same machine' may be used for gauging rollers'of'different kinds and sizes.

The block is provided with an upstand-ing portion 18 lconstituting abearing for the side of a roller 11 being gauged. Thebottomot'theblockisV inclined so that the upper edge of a roller lyingin the block is horizontal it the roller is of vstandard taper. Mountedvin the block 10 and in the npstanding portion-18 Vthereof are diamondpointed pins 19, wherebyth'e'roller is supported at the sides and at the.v large endso as to be easily rotated VVandwhereby it is? accuratelypositione'lv and held,

Pivotally mounted on the upper lug?) as byapin20-isa-leverv21 and abearing member`22 is mountedl so as to project above said 4lever 21.ROtata-bly mounted in the bear- Va roller 11 Vin the machine and rotateit-y while it is being gauged. The lever 21 mai7 be raised so as tocause the drive roll 26 to 'engage a roller 11 in the machine, and itmay be lowered so as to p'ull the' Ydrive the end of the screw in itsbearing 39 and wardly projecting yoke arms that enroll 26 away from theroller 1l so as to permit it to be removed from the machine and anotherroll to be inserted to be gauged. Mounted on the upper lug 3 is a stoplinger 27 that limits the downward travel of the lever.

The drive roll 26 is constantly rotated by means of a belt 28 thatpasses thereover. Secured to the base 2 underneath the spindle pulley 24is a support 29 in which .is mounted an idler pulley 3() over which thebelt 23 runs. Also mounted on the base 2 is a bracket 3l to which issecured a pulley 3.2 over which said belt 28 runs. Said pulley 32 ismounted on a shaft 33 that is constantly rotated in any manner,.as bythe drive belt 34 and pulley 35 shown in Fig. 1.

Mounted in the housingl are counterpart gauging mechanisms each of whichis provided with a contact lever 36 that is rotatably mounted on ashaft`37 in the housing. The contact levers 36 are spaced apart so as tomake contact with a roller 1l near the endsdle with a righthand threadand on theother side a lefthand thread. The ends of the screw 38 extendthrough the housing and are provided with suitableJ bushings 39. One endof the screw 38 is provided with Aa knob 40 by which the screw may inwhich is screwed a lockscrew 42 that is provided with a suitable knob 43for turning it.l When the lock screw 42 is screwed tight intotheadjusting screw 38 it expands locks the adjusting` screw againstrotation.

On each threaded portion of the adjusting screw 38j is a threaded ring44 that has upgage a shouldered ring `46 on one of the Contact levers.'Thus, by loosening the adjusting screw 33 and then `turning it, theContact levers 36 may be brought together or moved apart, therebyadjusting the gauging mechanism for any desired length of roller.

The end of each contactflever 36 project-s through a slot in the housingand terminates above the' roll block 10. Mounted on the underside ofeach lever 36 is a strip 47, preferably of spring metal in the forwardend of which is mounted a diamond 48 for maklof the housing.

sponding contact lever 36 is a light spring 53 that tends to prevent thecontact lever from falling ldown too far when the roller lthat has beengauged is removed from the machine. j V

A toe 54 at `the rear end of each contact lever v36 bears against aprojecting portion 55 of a lever 56 that is pivotally mounted on ashaft' 57' in the l. housing. The end-s of the shaft are mounted inbushings 57a in the side walls of the housing. Said projecting portion55 is wide enough so that the contact levers 36 may maintain contacttherewith in all of their positions. Pivotally` secured to a shoulder onleach lever 56 is a segment gear 59 that has a flat spring 60 securedthereto. On the lower part of each lever 56 is a pin 6l that ridesbetween the segment gear 59 and the spring 60.` The spring 60 is strongenough to normally hold the pin 6l' against the segment gear so that thetwo move together,vbut in case of mishandlingfthe machine the spring 60yields l and prevents the gauging mechanism from being damaged. v t

Secured to each pin 61 and to the rear wall of the housing l'is a spring62 that tends to return the gauging-.mechanism to its` original positionafter the gauging operation. j.

Each segment' gear 59 meshesl with a pinion 63 that is secured on ashaft 64 inV the housing. Thel outer end of'each shaft 64 is mounted ina bushing 64a in the side wall Mounted on the hub of each pinion 63 isan arin65 to which is secured a segment gear '66 that meshes withapinion 67 on a shaft 68 in .the upper part of the housing. Secured toeach pinion 67 is a po-inter 69 that moves in an arcuate slot 70 in thefront of thehousing. kAlong an edgeof each slot 70 is a graduated scale7l along which each pointer moves Each pinion 67 is provided with acounterweight 72 to counterbalance the weight of its pointer.

The housing is provided with a central brace member 7 3'between the twogauging mechanisms and said brace contains bearings 7 4 for lthe severalshafts that pass therethrough, the outer bearings being supported in thehousing walls as hereinbefore described.

The operation of follows:

` A gauging block the machiney is as 10 of the proper dimensions for thekind of rollers 11 to be gauged is placed'inposition onthe seat 9. j,Amaster roller of exactly standard shape and dimensions is placed on thesupporting pins 19 of the gauging block 10 under the contact points 48of the contact lever 3G. The hollow rod 4 is then raised or lowered byturning the nut`8 until one of the pointers 69 registers with zero onthe scale 71. The other pointer is then adjusted byv turning theAadjusting screw l52 of the contact lever 36 until said pointer alsoyregisters with zero on its scale 71. The contact'levers 36 are adjustedby means' of the adjusting screw 38 so Vthat the contact points 4&8 arenear the ends of the roller 11. After the above adjustments the machineis ready for gauging.

The drive roll 26 is' constantly rotated as above described. By pullingdown on the lever 21 the drive roll is Amoved away from the gaugingblock 10 and av roller 11VA is placed thereon in position tobe gauged.The lever 21 is then raised until'the drive roll 26 contacts with androtates the roller 11. The position of the pointers 69 along the scales71 shows the size of the roller. The position of the pointers 69 withrespect to each other shows the taper. If the roller is of the propertaper, the pointers 69 will be opposite each other (that is, pointing tothe .support, a pair of spaced independent consame graduation on thescale); whereas if the roller is ott-taper, the pointers will be spreadapart, the distance of the spreading showing the amount that the rolleris 0H- taper, and the direction in which the roller is off-taperdepending upon which pointer is above the other. As the roller 11 isrotated, the pointers 69 will move back and forth along the scale if theroller is out-ofround; whereas they will remain stationary if the rolleris truly circular.

The gauging machine herein described has numerous advantages. It enablesrollers to be gauged for size, taper and o-ut-o-roundness at onehandling and one setting, instead of requiring a separate gauging foreach of said items. The machine is adapted for use with rollers ofvarious sizes on account of the fact that thev gauging block isremovable.

Obviously, numerouschanges may be made without departing from theinvention and I do not wish to be limited to the precise constructionshown.
